Plot: Minato is a total loser. He's failed to make it into college twice, he's unpopular with women, and he's unemployed. Talk about classic-useless-shounen-harem-male-lead... But wait... There's more - he's actually an Ashikabi - one of a mysterious set of "masters" in an awesome battle royale between hordes of cute girls called "Sekireis."

Main Characters

Minato Sahashi: The main character. His family consists of a mother, a younger sister, and a father - A character which is little known. He failed the entrance exam to college twice. He met Musubi by a stroke of luck after failing the exam the second time while Musubi was being attacked. He is an Ashikabi - a person that can "wing" Sekireis - in an elimination battle. He has so far winged five Sekirei. He has a passive personality and is said to have gone along with what ever his mother and sister has said since childhood.

Asama Miya (Sekirei No.01) : She is the landlady of Izumo Inn. She specialises in swordmanship. She had a husband who previously worked as a researcher at MBI, but he died of reasons yet to be revealed. She never refuses anyone that needs shelter but prohibits fighting in her house. She trains both Musubi and Tsukiumi as their request to assist them to win the Sekirei battle. its still not clear if she has been winged or not.

Matsu (Sekirei No.02) : A computer hacker that lives in a secret room of Izumo Inn. She is also Minato's third Sekirei. She appears to be a bit perverted but is very smart. She is chased by MBI and that is the reason she lives in a secret room. It has yet to be revealed if she has any powers.

Kazehana (Sekirei No.03) : She becomes Minato's fifth Sekirei and her power is wind (derived from her name "kaze" which means wind and "Hana" which means flower). She meets Minato at the "Izumo inn" and seems to know his father (was possibly in-love with him and wanted to his Sekirei). Because of Minato's possible resemblance to his father, she begins to have feelings towards him and eventually persuades to Minato to make her his Sekirei. She later address herself as minato's new wife.

Karasuba (Sekirei No.04) : Her nickname is the "Black Sekirei". She is considered MBI's dog and her Ashikabi is Natsuo. She appears to be on bad terms with Miya. Her weapon of choice is a katana, and she probably is as strong as miya. She made a promise with Musubi that they would be the last two sekireis standing. She used to pair up with Yume in the past. Her intent is still unclear as of yet.

Mutsu(Sekirei No.05) : little we know about him except the fact that he is a swordman and his ashikabi is Mikogami Ayato

Homura(Sekirei No.?) : He defines himself the sekireis' guardian, his power is fire and he has not been winged yet(though he starts reacting to someone at a certain point) he often interrupts Hikari and hibiki's fights and side with the unwinged sekireis; actually he has a special body and lately even started changing gender because of his reaction towards an ashikabi, he lives at izumo inn as "Kagari", a popular host club entartainer and noone except miya uzume and matsu know his/her identity

Yume (Sekirei No.08) : This misterious Sekirei used to associate with karasuba and called herself the sekirei of "fate"; her power is light and in the past she killed herself to save Musubi's life (she was still a kid ) by giving Musubi her own "tama" (the core which let sekireis live and use their powers). She once temporary took over Musubi's body after having been knocked down, because Minato's warm heart somehow woke her up

Tsukiumi (Sekirei No.09) : She is Minato's fourth Sekirei and her power is water (derived from her name "umi" which means the sea). She contacted him over a dream saying that she would kill him but, when they finally met she was persuaded into becoming his Sekirei. ( ch.22-23) She says that she is Minato's legal wife.at the beginning she wanted to be the strongest to demonstrate that ashikabi were not necessary to win but later she confies to miya that her only goal is to get stronger to protect and live together with her ashikabi forever.

Uzume (Sekirei No.10) : she lives in Izumo inn and her ashikabi is a young ill girl whose name is Chiho: actually she is being hosteage in the hospital and Uzume is then forced to fight against whoever she is told to by her blackmailer (probably one of Higa guys or Izumi himself). she cover herself during the "hauntings" so everyone else refer to her as the "Hire" sekirei. she acts friendly with minato and his sekirei but she never confides her problems to them.

Musubi (Sekirei No.88) : The heroine. Minato's first Sekirei. She met Minato when she fell out of the sky. She is a power-Strength-type Sekirei. After hearing Tsukiumi say that she is Minato's wife she decides that she is gonna be his wife too. She is very naive and often says things she does not understand. She also eats a lot.

Kusano (Sekirei No.108) : She is often called Ku-chan but was referred to as the "Green Girl". She is Minato's second Sekirei. She calls him Onii-chan (Japanese term for 'Older brother'). She has power over plants-to make them grow.
